The research on enclosure noise control is caused more and more attention. The key of noise control is to grasp physical essence about enclosure sound-structure coupling field. The research work has been carried out on a enclosure model of two simly supported flexible plate and four rigid plates. The research is focused on sound –structure coupling field analysis of the enclosure when applying primary forces on two flexible plate simutaneously. At the constraint condition of average acoustic potential energy(AAPE) formulars of enclosure sound–structure coupling field is derivated. The simulation show the follow conclusion: first, the wave energy transfer path is from primary force flexible plate to acoustic cavity, then to another flexible plate, and then feedback to acoustic cavity. Second, when structural natural frequences are the same as acoustic natural frequencies of the enclosure, the noise reach the maximum value. The third, when applying primary force on Plate a and on Plate b simutaneously, the wave energy transfer path and The relation of sound-structure coupling are more complex than only applying force on one plate.

In the present paper, the coupling numerical analysis of 3D flow field and temperature field inside a marine generator was analyzed based on coupling field analysis method. The overall flow-temperature field models consist of the marine generator stator and rotor and flow passage and the air gap. Numerical analysis of flow-temperature field of marine generator were simulated by the finite volume method. The velocity and pressure distribution of fluid inside flow passage and the temperature field distribution of stator and rotor of marine generator were obtained. The present results showed that, the coupling field analysis method of overall flow-temperature field with air gap, stator and rotor can reflect the complexity of the air flow more clearly, and the value of flow and temperature field were more reliable. The results also contribute theoretical basis on optimization of ventilation struture of generator.
